Wärtsilä energy storage solution will minimise Canadian college’s Global Adjustment Charge

  • Wärtsilä’s GridSolv optimised storage technology integrates with GEMS software to deliver powerful and reliable generation performance.

The technology group Wärtsilä will supply a 2 MW / 5.4 MWh state-of-the-art energy storage system to Ontario, Canada based Alectra Energy Solutions, a subsidiary of Alectra Utilities. The system is to be installed at Georgian College in Ontario and is expected to notably lower the facility’s power costs by using energy storage to reduce electricity consumption when the electricity demand is peaking. This will decrease the College’s Global Adjustment Charge, which is a fee billed to all hydro customers in the province under Ontario’s 2009 Green Energy Act. These charges are typically 60% of the total annual electricity bill. The order with Wärtsilä was booked in December 2019.

The specified Wärtsilä system includes the company’s containerised GridSolv solution with lithium ion batteries, inverters, and all balance of plant equipment. The system is controlled by Wärtsilä’s GEMS proprietary advanced energy management system. GEMS enables the batteries to be charged when the electrical load is less than a pre-determined limit, and to discharge the batteries during peak loads, thereby minimising consumption from the grid. Furthermore, by its ability to respond to energy price arbitrage fluctuations, GEMS can charge the batteries when the price is low and discharge them when the price rises. GEMS is also capable of responding appropriately to higher winter energy demand. 

“Ontario is committed to achieving a sustainable power supply and conforming with this objective by seeking a zero-emissions solution was important to us,” said Angela Lockridge, Georgian College Vice President, Student Success and Corporate Services. “The Wärtsilä energy storage solution will help to significantly reduce the College’s electricity costs while supporting Ontario’s climate change mitigation strategies.”

Wärtsilä’s Risto Paldanius, Director, Business Development, Energy Storage and Optimisation, commented: “The system will be used in Ontario for effective power management. Managed by our advanced GEMS software, it is a highly efficient means for controlling demand charge type costs. By responding to Global Adjustment peak discharge events to cover the load, the system will deliver significant economic and environmental benefits to the customer.”

The Wärtsilä system is scheduled to be delivered, installed and commissioned in autumn 2020 and the delivery will mark further market expansion for Wärtsilä in Canada.

GEMS is the leading energy management software platform globally, enabling use-case applications, optimising more than 70 system portfolios, and integrating renewable thermal generation assets worldwide.
